Abstract
Description
Technical Field
[0001] This utility model applies to the field of automated assembly line equipment technology, and provides a foundationless sliding plate line track with an automatic opening and closing mechanism. Background Technology
[0002] In automotive manufacturing plants, skateboard transport is a common form of material handling. Skateboards move along skateboard tracks installed on the workshop floor, which typically run the entire production line. However, this method has significant drawbacks: when AGVs or other transport equipment need to cross the skateboard tracks, they must detour or use bridges, tunnels, or other alternative routes. These methods either lead to low transport efficiency or require substantial construction costs. Especially in modern smart factories, where AGVs are used increasingly frequently, this track setup severely restricts overall factory logistics efficiency. Furthermore, traditional skateboard track structures are fixed and cannot be flexibly adjusted to meet the demands of modern flexible production. Therefore, a new type of skateboard track structure is urgently needed that can provide convenient crossing channels for AGVs and other transport equipment while ensuring normal track passage, thereby improving overall transport efficiency and reducing construction costs. Utility Model Content
[0003] Therefore, this utility model provides a foundationless skateboard track with an automatic opening and closing mechanism. Through the automatic opening and closing mechanism, when AGV trolleys and other transportation equipment need to pass through the skateboard track, a gap can be provided at a designated position on the skateboard track to facilitate passage.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a foundationless sliding track with an automatic opening and closing mechanism, comprising a front opening track and a rear opening track. At least two automatic opening and closing track mechanisms are provided between the tail end of the front opening track and the beginning end of the rear opening track. The front opening track includes a first front track and a second front track arranged in parallel. The rear opening track includes a first rear track and a second rear track arranged in parallel. The first front track and the first rear track are collinear, as are the second front track and the second rear track. At least one automatic opening and closing track mechanism is provided between the first front track and the first rear track, and between the second front track and the second rear track. Each automatic opening and closing track mechanism includes a track rotating seat and a drive device rotating seat. The track rotating seat rotatably houses the movable opening and closing track, and the drive device rotating seat rotatably houses a track rotation drive device. The track rotation drive device is drivenly connected to the movable opening and closing track for driving its rotation.
[0005] Furthermore, several rail rotation support wheels are provided at the bottom of the opening and closing movable rail.
[0006] Furthermore, the automatic opening and closing rail mechanism also includes a movable rail fixing unit. The movable rail fixing unit includes a rail merging fixing block and a rail merging limiting push rod facing the rail fixing block. When the opening and closing movable rail rotates to be collinear with the first front rail or the second front rail, the rail merging limiting push rod can move closer to the rail merging fixing block and finally clamp the opening and closing movable rail between the rail merging fixing block and the rail merging limiting push rod.
[0007] Furthermore, the automatic opening and closing rail mechanism also includes a rail rotation limiting block, which can abut against the side of the opening and closing movable rail when the rail rotates to a certain angle.
[0008] Furthermore, the track rotation drive device is a linear drive cylinder or a linear drive hydraulic cylinder. The track rotation drive device includes a drive cylinder, a telescopic rod is slidably sleeved on the drive cylinder, the drive cylinder is rotatably connected to the linear rail rotating seat, and the end of the telescopic rod away from the drive cylinder is rotatably connected to the side of the opening and closing movable linear rail.
[0009] Furthermore, a fixed guide rod is provided on one side of the second front end rail and one side of the second rear end rail, and a movable guide rod is provided on one side of the opening and closing movable rail of the automatic opening and closing rail mechanism located between the second front end rail and the second rear end rail.
[0010] Furthermore, the number of automatic opening and closing rail mechanisms is four, with one automatic opening and closing rail mechanism respectively provided at the tail end of the first front rail, the tail end of the second front rail, the front end of the first rear rail, and the front end of the second rear rail.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, a notch is made in the skateboard track, and a rotatable movable track is installed at the notch. The movable track can rotate to allow the skateboard track to have two passage states. In the first state, the movable track is collinear with the front and rear tracks of the opening, allowing the skateboard to pass normally. In the second state, after the movable track rotates a certain angle, a passage is opened across the skateboard track between the front and rear tracks of the opening, allowing AGVs and other equipment to pass through the skateboard track, thus improving the overall material transportation efficiency of the production line without requiring high construction and modification costs.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example 1, refer to Appendix Figure 1This utility model provides a foundationless sliding track with an automatic opening and closing mechanism, including a front opening track 100 and a rear opening track 200. At least two automatic opening and closing track mechanisms 300 are provided between the tail end of the front opening track 100 and the beginning end of the rear opening track 200. The front opening track 100 includes a first front track 110 and a second front track 120 arranged in parallel. The rear opening track 200 includes a first rear track 210 and a second rear track 220 arranged in parallel. The first front track 110 and the first rear track 210 are collinear, as are the second front track 120 and the second rear track 220. An automatic opening and closing track mechanism 300 is provided between the first front track 110 and the first rear track 210, and between the second front track 120 and the second rear track 220. (See attached diagram.) Figure 5 As shown, the automatic opening and closing rail mechanism 300 includes a rail rotating seat 310 and a drive device rotating seat 340. The rail rotating seat 310 is rotatably equipped with an opening and closing movable rail 320, and the drive device rotating seat 340 is rotatably equipped with a rail rotation drive device 330. The rail rotation drive device 330 is drivenly connected to the opening and closing movable rail 320 and is used to drive the opening and closing movable rail 320 to rotate. The automatic opening and closing rail mechanism 300 realizes the rotation of the opening and closing movable rail 320 through the cooperation of the rail rotating seat 310 and the drive device rotating seat 340. The linear guide rotator 310 can be designed as a structure fixed to the ground or track foundation. The drive device rotator 340 is connected to the linear guide rotator 310 through bearings or hinges to ensure that it can rotate freely. In this embodiment, the track rotation drive device 330 adopts a linear drive cylinder or a linear drive hydraulic cylinder. The track rotation drive device 330 includes a drive cylinder, and a telescopic rod is slidably sleeved on the drive cylinder. The drive cylinder is rotatably connected to the linear guide rotator 310. The end of the telescopic rod away from the drive cylinder is rotatably connected to the side of the opening and closing movable linear guide 320. Several linear guide rotation support wheels 350 are provided at the bottom of the opening and closing movable linear guide 320 to keep it stable during rotation, reduce friction, and ensure the smooth operation of the linear guide.
[0026] In one embodiment, to improve the stability of the opening and closing movable rail 320 when it rotates to the parallel rail condition, a movable rail fixing unit is also provided in the automatic opening and closing rail mechanism 300. The movable rail fixing unit includes a rail parallel fixing block 360 and a rail parallel limiting push rod 370 facing the rail fixing block. When the opening and closing movable rail 320 rotates to be collinear with the first front rail 110 or with the second front rail 120, the rail parallel limiting push rod 370 can move closer to the rail parallel fixing block 360 and finally clamp the opening and closing movable rail 320 between the rail parallel fixing block 360 and the rail parallel limiting push rod 370 to avoid deviation caused by vibration or other external forces. The linear guide rail limiting push rod 370 can be moved by hydraulic, pneumatic or electric drive. The specific implementation method can be selected according to the needs of the actual application scenario. In order to ensure that the automatic opening and closing linear guide rail mechanism 300 also includes a linear guide rail rotation limiting block 380, the linear guide rail rotation limiting block 380 can abut against the side of the opening and closing movable linear guide rail 320 when the opening and closing movable linear guide rail 320 rotates to a certain angle.
[0027] In one embodiment, a fixed guide rod 400 is provided on one side of the second front rail 120 and the second rear rail 220. A movable guide rod 500 is provided on one side of the opening and closing movable rail 320 of the automatic opening and closing rail mechanism 300 located between the second front rail 120 and the second rear rail 220. When the opening and closing movable rail 320 rotates to be parallel with the opening and closing front rail 100 and the opening and closing front rail 100, the movable guide rod 500 will be collinear with the fixed guide rod 400, which plays an additional limiting and guiding role when the slide moves on the rail.
[0028] The technical solution of this application solves the problem that the sliding track cannot provide a passageway for other transportation equipment during material transportation by setting an automatic opening and closing track mechanism 300. Specifically, when the AGV or other transportation equipment needs to cross the sliding track, the automatic opening and closing track mechanism 300 can drive the opening and closing movable track 320 to rotate, separating it from the front or rear track. At this time, as shown in the attached... Figure 2 As shown, this provides a passageway for transport equipment. Therefore, there is no need to detour or use bridges, tunnels, or other alternative routes, improving transport efficiency and reducing site construction costs. Compared with existing technologies, the technical solution of this application has the advantages of simple structure, convenient operation, and high degree of automation, and can provide a convenient passageway for other transport equipment without affecting the normal passage of the skateboard line track.
[0029] Example 2, refer to Appendix Figure 3 Appendix Figure 4Based on Embodiment 1, the number of automatic opening and closing rail mechanisms 300 is set to four. One automatic opening and closing rail mechanism 300 is set at the tail end of the first front rail 110, the tail end of the second front rail 120, the front end of the first rear rail 210, and the front end of the second rear rail 220. When the AGV or other transportation equipment needs to pass through the sliding track, the opening and closing movable rails 320 of the four automatic opening and closing rail mechanisms 300 rotate to the left and right sides respectively. Compared with the solution in Embodiment 1, the width of the passage in this embodiment is doubled, which can better accommodate larger equipment.
[0030] In summary, this utility model provides a low-elevation lifting fork transfer mechanism applicable to vehicle welding workshops, which can transfer skids and body parts between two extremely low-elevation conveyor lines without the need for pre-embedded foundation pits, greatly reducing the construction cost of the production line.
